Renzo Piano

When you design a building, you start from a general philosophy, and you come down, and you start from detail and come up. Only the theoretical architect believes that you can make the concept and then sometime, somebody will come to build it.

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.
